Carrier introduces residential R32 air-to-water heat pump
Carrier, a US-based heating solutions provider, has launched a new series of air-to-water heat pumps for residential buildings.
“This marks the company’s first domestic hot water solution integrated into an air-to-water heat pump product for North America, offering an advanced, sustainable solution for homeowners and builders seeking energy-efficient alternatives in home heating, cooling, and domestic hot water,” the company said in a statement. “It enables versatile integration for radiant heating, forced air, and chilled panels.”
The DWH A2W Heat Pump uses R32 (difluoromethane) as a refrigerant and reportedly achieves a coefficient of performance (COP) of 4.9. Noise levels range between db(A) 52 and db(A) 56.
The system includes an outdoor unit that makes it easier to use it for residential new builds, as well as retrofits, according to the manufacturer.
“The system is kitted to include the heat pump, hot water tanks, an indoor control panel, and all the main fittings required for installation, all under a single part number,” the company stated. “This comprehensive approach significantly simplifies the selection process and eliminates the need for contractors to determine and size necessary fittings. Additionally, the system offers multiple DWH tank sizes to accommodate all A2W Heat Pump capacities, making it a versatile solution for a wide range of applications.”
Carrier did not reveal more technical details about the new product.

This is great hopefully it is a set and forget it product.
I do have wonder about indoor noise and replacement cost of the tank as many insurance companies require tank replacement after ten years.

We are on stand alone power off the grid . I am just wondering how much power these air heat pumps take out of your power supply per day. We only have a 5 kwt system in place therefore I’m just wondering if your system is suitable for us . Kind regards Mark
@Michael Oort The reason it’s news is because there are very few A2W heat pump options available in the US and R290 isn’t legal to use for residential in a significant enough quantity in the US at this time. Also the COPs between the two aren’t comparable. The WeHeat is A7W27 and the Carrier is using A5W110.
I’m pretty sure this Carrier is a rebranded Veissmann 100-AW which was developed in Germany.
Don’t really understand why this outdated technology catches headlines. WeHeat (Based in the Netherlands) for example makes R290 heatpump with a COP of 6 and 37 dB noise level. Goes down too much lower temperatures as well -20Celcius.
